The Ecology of Activism: Professional Mobilization as a Spatial Process

This article develops an ecological theory that shifts the paradigm of professional mobilization from causes to relational spaces. It analyzes different species of activist professionals by locating them in an ecology of activism and examining how collective action emerges from their boundary work with the ecology's increasing density and consolidation. It empirically grounds the theory by explaining the political activism of Chinese lawyers in the early twenty‐first century and how it led to a government crackdown in 2015. Using interviews, online ethnography, and archival data collected from 2005 to 2017, the research demonstrates that Chinese lawyers’ political mobilization has experienced three stages: (1) vacancy and isolation (2000–2007), (2) spatial consolidation (2008–2011), and (3) boundary work (2011–2015). The study has implications for theories of social space and for understanding professional mobilization in authoritarian contexts and beyond.     

Predicting body fat using weight–height indices

While body fat is the most accurate measure of obesity, its measurement requires special equipment that can be costly and time consuming to operate. Attention has thus typically focused on the easier to calculate body mass index (BMI). However, the ability of BMI to accurately identify obesity has been increasingly questioned. This paper focuses attention on whether more general body mass indices are appropriate measures of body fat. Using a data set of body fat, height, and weight measurements, general models are estimated which nest a wide variety of weight–height indices as special cases. In the absence of a race and gender categorisation, the conventional BMI was found to be the appropriate index with which to predict body fat. When such a categorisation was made, however, the BMI was never selected as the appropriate index. In general, predicted female body fat was some 10 kg higher than that of a male of identical build and predicted % body fat was over 11 percentage points higher, but age effects were smaller for females. Considerable racial differences in predicted body fat were found for males, but such differences were less marked for females. The implications of this finding for interpreting recent research on the effect of obesity on health, society, and economic factors are considered.     

The Pursuit of Continuous Improvement in the Field of Intergenerational Relationships: The Discipline of the Second Curve

This article presents a case for the field of intergenerational relationships to embrace the challenges associated with progressing its reputation, boundaries, and potential in the twenty-first century. The concept of the Sigmoid curve based upon curvilinear logic and the discipline of the second curve is introduced as a means of understanding how individuals, organizations, and institutions need to deal with the challenge of constant renewal as a consequence of rapid social change. The field of intergenerational relationships is challenged to align itself with the discipline of the second curve by (1) improving the impact of research through knowledge-based transfer and (2) exploring new fields of inquiry in the interest of maintaining and advancing relevance and legitimacy.     

Forecasting obesity trends in England

Summary.  Forecasts of trends in obesity in England for 2010 are produced by treating the available data, which contain the proportions of the population, categorized by age and sex, falling into different body mass index ranges, as compositional data sets, so that the implicit simplex restrictions are automatically satisfied. Forecasts are calculated by using linear trend models for the log-ratio transformations and are accompanied by prediction regions. The advantages of treating data on proportions compositionally are emphasized and compared with forecasts that have been obtained by ignoring this restriction.     

The social and demographic impact of the Southeast Asian Crisis of 1997–99

When an unexpected financial crisis overtook Southeast Asia in 1997 planners and policymakers feared that the economic difficulties would unwind two decades of remarkable economic and social development. Newspaper headlines spoke of massive increases in poverty, unemployment and malnutrition, and it was speculated that family planning programs would collapse and fertility would rise dramatically. Infant and child mortality and maternal mortality were also expected to increase. This paper briefly reviews the onset of the financial crisis as a background for assessing whether speculations about die demographic and social effects tallied with reality. It is found that these effects were neither as dramatic nor as easy to monitor as some of the public debate implied. The general lesson is that the most serious social and demographic problems were not so much the products of crisis as embedded in chronic weaknesses that had become entrenched in times of economic growth. The crisis exposed these weaknesses.     

Hunger: The Silent Epidemic Among Asylum Seekers and Resettled Refugees

Refugees and asylum seekers face challenges after arriving in a host country. They carry the trauma that they may have experienced in their countries of origin, during fight, and in countries of asylum. Other stressors impact on their adjustment after arriving in the United States including basic needs such as food, clothing, and shelter. This is a retrospective review of data collected as part of a needs assessment by a program, which serves survivors of torture and refugee trauma. Asylum seekers (n=65) and refugees were compared (n=30). Asylum seekers were more apt to be from Africa (p<.001), need family reunification (p=.027), speak more languages (p<.001), suffer from political persecution (p<.001), move from place to place due to not having a permanent place to live (p=.031), and be unable to contribute to the rent (p<.001). Unadjusted, asylum seekers were also more likely than refugees to have gone to bed hungry in the previous two weeks (p<.001) or since arriving in the United States (p<.001). Refugees were more likely to be eating more food now than before feeing, and asylum seekers the opposite (p<.001). Being an asylum seeker made one 3.7 times more likely to suffer from food insecurity than being a refugee, and 5.3 times more likely to not have work authorization. Among asylum seekers, adjusting for gender, age, education, lack of permanent housing, English fluency, and self-reported health status, not having work authorization made one 5.6 times more likely to suffer from hunger. Independently, being a torture survivor made one 10.4 times more likely to suffer from hunger. Asylum seekers must wait 150 days before applying for asylum in the United States. For humanitarian reasons, mandatory-waiting periods for work authorization for asylum seekers should be eliminated.
